Take the next digit (7) from the dividend and append it to 102, then repeat: 1027 / 238

Going ahead to step 4:
1027 divided by 238 is 4 with a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 75 after subtracting 952 from 1027.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 238

Moving on to step 5:
757 divided by 238 is 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 243.0
Subtract 714 from 757 to get 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 238

Advancing to step 6:
The number 238 fits into 435 1 times, leaving a remainder of 197.
Use 1 as the next digit of our solution. 
Result so far: 2431.0
Subtract 238 from 435 to get 197.
Bring next digit (5) of the dividend behind the 197 and repeat the process: 1975 / 238

Advancing to step 7:
238 can be fit into 1975 8 times, resulting in a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 24318.0
Subtract 1904 from 1975 to get 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 238

On to step 8:
238 goes into 717 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 243183.0
Subtract 714 from 717 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
238 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 243183.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 238, we get 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 243183.01
The remainder is 62 after subtracting 238 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
238 can be fit into 620 2 times, resulting in a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 243183.012
If we take 476 away from 620, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 12:
238 can be fit into 1440 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 243183.0126
Deduct 1428 from 1440 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
238 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 243183.0126
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
238 can be fit into 1200 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 243183.012605
If we subtract 1190 from 1200, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 15:
When dividing 100 by 238, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 243183.012605
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 16:
If we divide 1000 by 238, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 243183.01260504
Deduct 952 from 1000 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 243183.01260504 and a remainder of 4.8e-08.
